[0002] In factories or other processing and production environments, when carrying out processes such as mixing, in order to ensure that the materials can achieve the corresponding processing results under the required processing environment conditions, sensors are usually used for real-time monitoring and control. However, due to the different purposes and needs of factory mixing processing, the diversification of material types, the increase in processing volume, and the complexity of the mixing process, the monitoring feedback method of the sensor is limited.

The production method that allows a certain proportion of production content to be converted into impurities through redundant settings is not friendly enough to achieve the product's finishing goals, and additional purification steps may be required in the future, affecting processing efficiency.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0047] like Figure 1 The scene-assisted guidance method for multi-gas detection provided by an embodiment of the present invention comprises the following steps:

[0048] S10, acquiring trace gas detection data of multiple nodes in real time based on the distributed terminal, wherein the trace gas detection data is used to characterize the gas composition and content information of the current node at the current time;

[0049] S20, establishing a twin fitting model, and assigning basic participation information of the current operation behavior to it, performing wide-area condition simulation according to the assigned data, and obtaining fitting operation results under different conditions, wherein the basic participation information is used to characterize the processing participating materials, processing execution process and corresponding operation goals of the operation behavior;

[0050] S30, matching the gas detection data with the fitting operation result to obtain the current actual operation state, and if the actual operation state is inconsistent with the preset operation stage requirement determination, generating an auxiliary guidance requirement;

[0051] S40, in response to the auxiliary guidance demand, matching the corresponding guidance adjustment object according to the difference between the actual operation state and the operation stage demand to establish an auxiliary guidance cycle, until it is determined that no corresponding auxiliary guidance feedback is generated, the guidance adjustment object includes processing procedure parameters, temperature and humidity parameters and solvent environment parameters.

[0052] In this embodiment, a scene-assisted guidance method for multi-gas detection is provided. By using trace detection of multiple gases as an indicator of production operations and experimental progress, the actual progress status of the production operation can be accurately and intuitively judged through the gas generation in the process. When a very small amount of non-target process gas is generated in a certain processing operation, the deviation of the operating environment can be effectively evaluated, and the material environment and the operating environment of the processing operation can be adjusted and controlled in a timely and effective manner to ensure the target achievement effect of the processing. In the prior art, for example, in various scenarios such as product processing and mixing, or chemical treatment of garbage, when the generated gas appears in some target processes, it means that the environmental variables of the processing and mixing (or reaction) may deviate from the optimal environment, and guidance adjustment is required, that is, the generation of gas or the change in gas concentration is used as an indicator of the actual progress of the product processing and mixing, or the chemical treatment of garbage. By monitoring the generation of these gases, it is judged whether the process progress is normal. Specifically, a trace gas detection scheme is used here in conjunction with a data fitting processing method of twin simulation. Through trace gas detection, the real-time gas generation situation can be judged, and By using twin simulation, simulation can be performed based on the content of the processed materials (including impurities contained in the materials, for example, when processing materials containing S, according to the conventional process, it is assumed that related sulfides of solid and liquid substances should be produced, but in the detection, it is found that gaseous substances such as sulfur monoxide and sulfur dioxide are produced) and the corresponding processing conditions to determine the mixing state and related physical and chemical changes under different processing conditions, including the type of gas substances generated; and then the actual measured gas content can be matched with the various fitted data states to determine the progress of the actual processing, so as to adjust the guidance and control according to actual needs; compared with the prior art, in a production environment such as a factory, when mixing processing is carried out, sensors are often used for monitoring and control. However, because the processed materials may be large in volume or the degree of mixing is complex, it is difficult for the sensors to fully obtain the parameter states of multiple internal regions, resulting in the inability to accurately determine the operating state, and it is also impossible to effectively and flexibly guide and control. A certain allowable error range can only be pre-set through redundant settings, which is not friendly enough for the realization of the product's finishing goals. The present application uses indirect detection and fitting to determine the internal state of the processed material, which effectively solves this problem.

[0053] like Figure 2 As shown, as another preferred embodiment of the present invention, the step of acquiring trace gas detection data of multiple nodes in real time based on the distributed terminal specifically includes:

[0054] S11, performing absorption characteristic detection on the gas in the monitoring interval based on the CRDS spectroscopy to obtain a spectral detection result in the current area, wherein the spectral detection result is used to characterize the absorption degree of light sources in different wavelength bands, and the CRDS spectroscopy is used to achieve non-contact high-sensitivity optical detection of trace gases;

[0055] S12, obtaining multiple conditional gas types under the current behavior-based participation information, calculating the spectrum detection results according to the spectrum absorption types of the multiple conditional gases, determining the absorption rates of the multiple conditional gases, and then deriving and obtaining the corresponding gas concentrations, wherein the conditional gases are used to characterize the gas types that may be generated during changes in operating environment conditions and various processing execution processes;

[0056] S13, the conditional gas type and concentration information obtained by the detection are marked with time and node information to establish trace gas detection data.

[0057] In this embodiment, the gas detection and acquisition step is further supplemented. The gas detection can determine the content of different components in the gas through spectral analysis of the local environmental gas, and then the specific analysis and judgment of the gas composition can be performed according to the gas type that may appear in the specific usage scenario. The CRDS spectroscopy method is adopted here to achieve this. The CRDS spectroscopy method is a very sensitive trace gas detection technology, which is suitable for the detection of low-concentration gases. Therefore, it is more suitable for the technical environment constructed by this embodiment. It can timely and efficiently detect and discover the trace non-target gases generated in the operation, and can detect the environmental state deviation earlier. Quickly realize the scene assignment guidance in the early stage of the operating environment deviation, so as to achieve the purpose of correcting the operating environment parameters.

[0058] As another preferred embodiment of the present invention, the twin fitting model is used to characterize the fusion effect development model of multiple different processing participating substances as different processing environments change during different processing execution processes, and is used to fit the conditions for the mutual reaction between substances in the relevant processing participating substances;

[0059] In the step of simulating wide-area conditions according to the assigned data, the wide-area conditions are used to characterize the possible occurrence range of external condition factors of non-material ratio variables, including the variable range of temperature and humidity, oxygen condition state, and the span range of solvent acid-base conditions. The fitting operation results are used to characterize the gas generation state under the current conditions, including the gas type and the corresponding generation content.

[0060] In this embodiment, the definitions and functions of the twin fitting model and wide-area conditions are clarified. The twin fitting model is essentially a physical and chemical analysis model trained with a large amount of data. After setting the material objects involved in the physical and chemical processing and the processing methods and environment, it can simulate the changes in the state of materials within a certain period of time (such as the degree of progress of chemical reactions); the wide-area condition fitting lists various possible external environmental states, so as to obtain the actual changes of material objects under different environmental states through the twin fitting model fitting, and obtain various possible intermediate states and products.

[0061] like Figure 3 As shown, as another preferred embodiment of the present invention, the step of matching the corresponding guidance adjustment object according to the difference between the actual operation state and the operation stage requirement to establish an auxiliary guidance cycle specifically includes:

[0062] S41, obtaining the operation phase requirement of the current processing execution process node, wherein the operation phase requirement is used to represent the requirement information of the controllable operation environment parameters in order to obtain the operation target at the corresponding processing execution process node;

[0063] S42, performing difference calculation based on the actual operation state obtained by matching and the operation stage requirement, obtaining actual state differences of multiple controllable operation environment parameters, and marking the corresponding controllable operation environment parameters as guidance adjustment objects;

[0064] S43, establishing an auxiliary guidance cycle based on the guidance adjustment object and the actual state difference, wherein the auxiliary guidance cycle is used to execute the guidance adjustment of the actual state difference, and perform trace gas detection and re-determine the actual operation state after the guidance adjustment.

[0065] In this embodiment, the steps for establishing an auxiliary guidance loop are described in detail. Through the previous multiple embodiments, it has been learned that there are mainly two parts of data here. One is the gas composition data actually detected. This data is matched by the array data under the wide-area condition fitting, and then the actual processing environment state of the material under the current gas composition data, that is, the actual operating state (such as temperature and humidity, etc.) can be understood; the second is the operating state actually required for the processed product at the current node during the operation (in order for the material to achieve the target processing result). Therefore, the difference between the two can be used to determine the parameter object that actually needs to be adjusted and the corresponding adjustment amount, and then the auxiliary guidance loop is established. This includes a loop attribute, that is, this process needs to be continuously performed to achieve a continuous and dynamic regulation process.

[0066] As another preferred embodiment of the present invention, the correction and update step of the twin fitting model is also included:

[0067] When the auxiliary guidance cycle is generated, the real-time operating status is obtained, and the status and content of various processing participating materials and controllable operating environment parameters in the real-time operating status are used as initial fitting parameters, and the initial fitting parameters are assigned to the twin fitting model, and the current trace gas detection data is used as the gas environment starting data.

[0068] In this embodiment, each adjustment corresponds to a different material environment. Therefore, in order to ensure the accuracy of the data generated in the subsequent twin fitting process, it is necessary to perform a second operation fitting based on the materials and environment matched in the first fitting to achieve accurate matching of the second trace gas detection results. Therefore, the purpose of this step is to achieve synchronization of the update of the data used in the twin fitting model fitting.
